Spencer never believed that Zack was feeling apologetic at all. A leopard can't change its spots.
Nathalia was an exception in the Carters. The rest were all creeps. Zack Carter was murderous when he was fifteen. Who would believe that he had changed in two years? Even if he did, why should Nathalia and Spencer forgive him? What he did was unforgivable.
Nathalia grumbled, "I don't understand. Who is it that wants to do me harm? It's so annoying." So much had happened lately, one surprise after another. She felt like there was someone in the dark watching her and manipulating her life and the worst thing was that she had no idea where they were hiding.
